Choose columns from list

Howdy. I've got monthly data that I receive across 2000 zones, of which I only need a few hundred. I have a list of the ones I need and I'm trying to use  table.removecolumns with the list as a reference but keep getting errors. I know I could manually just pick the ones I need, but where's the query fun in that? Sample data below, I can provide a sanitzed pbi book if needed

  • Hi Anonymous ,

     

    Please make sure the type of the list is in text format in the Power Query Editor instead of Desktop model. 

     

     

    Or you can try the Number.ToText function to convert the type of the list to text.

     

    = Table.RemoveColumns(#"Changed Type", List.Transform(pixellist, each Number.ToText(_)))

     

    If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.

  • Anonymous or you can add a step by removing a column and changing that remove column step to this

     

    in the following code, columntoremove is  a table that has a list of columns you want to remove and remove is a column in that table, you can change these values as per your table/column names

     

    Table.RemoveColumns(#"Some Ste",ColumnToRemove[Remove])
